The difficult thing with internet forums is that typed words often don't contain tone or are easily misinterpreted. While to Deborah, her response seemed concise, to you it appeared condescending and so an argument ensued. Deborah is a mod on here and a reputable breeder, so usually people looking for advice are usually willing to take it when offered from such a person. Granted, there is nothing wrong with questioning a breeder's opinion or asking for further evidence.
I get though. It's hard to accept that you are a victim of your local pet store. I find it deplorable what they do to make money and have complained to their management in the past about the condition of the reptiles they keep for sale. Their goal is to sell you as much as possible (usually including caging and lighting you don't need) and rarely employ people knowledgeable about how to take care of the reptiles they are selling. Like Pit said, they let people leave without buying a thermostat to control their UTH. I can't imagine how many burned snakes this has led to.
Anyways, I am far from being an expert, but your BP doesn't quite look like a normal to me. Maybe it is a Woma or something similar. It's definitely not a phantom spider as I've had one and yours looks nothing like it. Either way, you paid too much and you should at least write the store's customer service email and tell them about how you were overcharged and had a terrible experience. They may at least return some of your money for it. You absolutely have a right to be mad, but they won't know about it unless you complain.
Lastly, if you love your little BP, accept him and do your best to make him comfortable and happy. Remember in the end that these are living creatures and no matter what circumstance brought him to you, he's yours now to enjoy. Caring for reptiles brings me immense pleasure and I love being able to participate in their lives. All value for morphs and colors aside, any BP is an awesome pet.
